AUTOMATIC GRAIN WEIGHER AND REGlSTER.

SPECIFICATION forming part of Letters Patent No. 285,921, dated October 2, 1883.

Application filed April 111853. Nomodcl) To all when? it may concern:

l-le it known that I, \VI LLIAH BELL PATTER- sON, of Secor, in the county of Voodford, and in the State of Illinois, have invented certain new and useful Improvements in a Combination Graiirlfilevator and Automatic iVeigher and Register; and I do hereby declare that the following a full, clear, and exact desm'iption thereof, reference being had to the aceompanying drawings, and to the letters of reference marked thereon, making apart of this specili cation, and in which Figure l is a side elevation, partly in section, of my improved apparatus; Fig. 2, a longitudinal vertical section; Fig. I a view in perspective of the registering mechanism; Fig. 4, a side elevation of weighing and registering mechanism; Fig. 5, a side elevation of mechanism for operating the measure or receptacle; Fig. (5, a detail section through lower end of elevator; Fi 7,aview in perspective of one of the disehargespouts; Fig. 8, a detailed view to be hereinafter referred to.

This invention relates to certain new and useful. improvements in a combined grain-elevator and automatic weighing and registering apparatus, more especially designed for use in connection with a thrashing-machine; and to this end the invention consists in novel features of construction and combination and arrangement of parts, all as will. be hereinafter fully described, and set forth in the claims hereto annexed.

In the drawings, A represents the inclosingcase of the elevator supported in an elevated position by uprights a and stay-ropes a, and which case is provided with a hopper, a, through which the grain is discharged into the cups I), mounted or secured on an endless band, 13, adapted to be moved around rollers O 0, arranged, respectively, at the upper and lower ends of the elevator, the roller 0 being mounted in adjustable bearings 0, operated by screwbolts and nuts 0, connected by a cross-bar, 0 all as clearly shown in Figs. 2 and 6. The cups 1) have overlapping end projections, b, to pre vent grain from falling out at the ends of the cups over the sides of the belt in passing over the upper roller until it is dumped.

The registering aml weighing mechanism is arranged at and in the upper end of the elevator, and which I will now proceed to describe.

D represents a large disk attached to one side of the elevator-spout, and forming the back part of the inclosing-case and a support for the several parts of the registering mechamsm.

I represents a large ratchet-wheel provided with twenty ratchet-teeth, and mounted upon a solid central. shalt, 0, attached to the disk I). The wheel E is provided with a thimbleshaft, e,whieh slips over the solid central shaft, (1, and is extended outside of the disk I), and has attached thereto the indevhand 0 for llI- dicating on the dial-plate e the half-lmsl'iels of grain measure-(l.

F represents a second ratchetwvheel provided with a larger thimble-shaft, f, adapted to slip over the thimbleshaft c of wheel E, and is extended out a shorter distance than the thimble-shait c, and carries an index-hand, f, which registers one point for each revolution of the wheel E, the wheel F being of less diam eter and provided with ten ratchet-teeth.

G represents a third ratchet-wheel, of less diameter than wheel F, but having, the same number ofteeth. This wheel G has-also athimble-shaft, adapted to slip over, butjs shorter than the thimble-shaftf, and carries the shorter index-hand which registers one point to each revolution of the wheel F.

H H H are pivoted hooked levers or keepers for retaining the wheels E F (l until they are moved by mechanism to be hereinafter described, said levers being held in position by springs h 7! 71.

1. represents a pivoted lever fulcrumed on a lug, d, on one side of the disk I). This lever is provided at its lower end with a springpawl, '2', engaging the teeth of the wheel F, and is also provided with a downward]y-projecting spring-arm, 1', designed to engage a pin, 1' on the side of wheel Id, at each revolution thereof, by which the wheel. F is moved one tooth through the medium of pivoted lover I and pawl i. J represents a similar pivoted lever,

having a spring-pawl, j, adapted to engage the teeth on wheel G, and a springarm, j, adapted to engage a pin, f, on wheel F, at each revo lution thereof, for moving wheel G one teeth. (1 d are s nrings connected to disk I), and

lower end of a bar, K, which has at its upper end a pivoted pawl, k, that engages the ratchet-wheel of the registering mechanism, all as clearly shown in' Fig. 4. This scale-beam is also pivotally connected by a transverse bar,

m, (see Fig. 8,) to a similar supporting-bar, an, on the opposite side of the elevator, and

which bar m has a right-angled projection, m which forms the bearing for the measure or receptacle N. The measure or receptacle N, in the present instance, is divided into three transverse compartments, a, each of which-is Iailapted to hold one half-bushel of grain, and

has on its outer sides three projecting pins, n, for a purpose to be hereinafter described.

M represents a notched wheel mounted upon the extended end of the shaft carrying the upper roller, 0, which wheel M, in its revolution, strikes the upper end of a pivoted springlever, B, fulcrumed at the point 1', and provided at its lower end with a pivoted springpawl, r, that is adapted to engage the pinsun on one side of the measure or lpceptacle N, all

as clearly shown in Fig. 5. On the opposite side of the elevator-spout (see Fig. 1) is se-- cured a bar, 0, having a pivoted spring-arm, 0, that engages the pins n on the opposite side of the measure or receptacle N, to prevent the same from revolving too far after it has dumped or discharged the grain from one of its compartments.

An intermediate distributing-hopper, P, is placed immediately above the measure or receptacle N, to receive and discharge the grain (carried up, and discharged from the cups on the belt B) into said measure or receptacle.

The object of this hopper is twofold: first to distribute the grain evenly into the measure or receptacle, and, secondly, to prevent the momentum of the falling grain from affecting the scale-beam. Spouts T, of the shape shown in Figs. 1 and 7, or of any suitable shape, may be connected to the conveyer-spout for receiving the grain from the measure or recepta- .cle and discharging it into sacks, wagons, or

bins.

When my improved apparatus is used in connection with a thrashing-machine, the design is to derive the power through a sprocket belt that runs over a sprocket-wheel, S, (see Figs. 1 and 6,) that may be placed on either side of the elevator. A sprocket wheel and belt are preferred, as said belt can be run slack, and thus obviate any vibration being communicated from the thrashing-machine to the elevator, which might have a tendency to affect the registering and weighing mechanism.

Having thus fully described my invention, I will now proceed to set forth the operation of the same, which is as follows: When the measure or receptacle is suff ciently filled with grain to overbalance the weighted scale-beam, said measure or receptacle, in its downward or revolving movement, carries with it the lower end of lever B, causing its upper end to come in contact with the teeth of wheel M. This engagement throws pawl r against one of the pins n (see Fig. 5) and propels the measure forwardin the direction indicated by the arrow (see same figure) and insures the discharge of the grain. When the grain is dumped, the beam and weight fall, which operates the registering mechanism through the medium of the bar K, connected to said beam, and the pawl k, engaging and operating ratchetwheel E, which in turn communicates motion to the wheels F and G in the manner herein before described. As the measure is emptied,

or each compartment thereof, it is arrested in its further revolving movement by the springpawl o engaging one of the pins n, (see Fig.

1,) thus retaining the measure in proper posi- 2. The combination, with the revolving measure or receptacle N, having a series of compartments, n, and stop-pins n at both of its ends, of the spring-pawl o, pivotedlever R. having spring-pawl r, and the toothed wheel M, substantially as herein shown and described.

3. The combination, with a pivotal and weighted scale-beam carrying the revolving measure or receptacle N, with stops-pins n, and registering mechanism, substantially as described, operated through the medium of said beam, of the pivoted lever B, having spring-pawl r, and the revolving toothed wheel M, substantially as and forthe purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this 2d day of March, 1883. a I
